Hooked up with my first every guy with a humungous cock whilst in Manhattan recently. Easily 9" by 6.5". I was sucking him off and at a few points he took those last (several) inches and rammed them in and starting facefucking me. It was hot! Made me gag a bit from time to time but otherwise no worries.

Usually it's the other way round with me but never really found anyone that could go all the way down on me. Actually found it easier with his huge cock than smaller ones - smaller tickles more, bigger - there's just no saying no!
